TO ALL'WHOM IT'MAY CONCERN:

Be it known that T, ANDREW STUMP, of Bodega, county et' Sonoma, State'of California, have invented an Improved Churn; Aand I do lherebydeclare the following description and accompanying drawings aresufficient to enable any person skilled in the art or science to whichit most nearly appertains to make and use my said invention orimprovements without further invention or experiment. v

The object of my invention is to construct an improved, churn, by whichthe crea-ui can bc thoroughly agitatednand speedily converted intobutter, after which, by a simple contrivancc, it can be gathered, or theparticles brought together into a mass ready for working.

My invention consists of a long box of any desirable shape, but I'prcferonewhose cross-sections shall be square, as bcingitlic most effective.This box is supported horizontally, and revolves upon 'spindles ateither end. A second shaftpasses through the bom-bearing arms, and isrevolved by a crank in au opposite direction to the motion of the churn,until the butter is formed,lwhen itis fastened so as toremain stationarywhile the box is revolved, thus bringing the particles together into a.mass.

'Io more fully explain my invent-ieu, reference is had to'theaccompanying drawings, forming alpart of this specicationof which-Figure 1 is aside sectional elevation.

`Figure 2 is an end view.

Similar letters of' reference in each of the figures indicate likeparts.

A is a churn, in the form of an oblong box, whose cross-section is asquare. This box is supported horizontally upon the frame B B by theaxles or spindles a a, upon which it is revolved by means of the crankC. A door or cover, D, serves to introduce and withdraw the cream orbutter, while thc buttermilk is drawn ol by the opening at E. v

The axle a is made hollow, and has the smaller axle li passing throughit, and actuating the longitudinal shaft F, which has projecting from itthe arms c c. This shaft is turned in a direction opposite to the motionof the churn A, by means ofthe crank, G.

By means of these opposite motions, the cream can be thoroughlyagitated, and converted into butter in a very sliort time. When this isVdone, the butter will be scattered Vthrough the milk in smallpartielles, which can begatliered by withdrawing the shaft F, andrevolving them'box slowly for a short time. The axle b is retained inplace by the clasp H, which shuts down over it, and by means of ashoulder prevents 'it from slipping out. After withdrawing' the shaft F,the axleb is' prevented from turning by the ,pin I, which is passedthrough-fthe cap'. H, and the axle at '[or tho shaft F maybe left in thechurn, and keptstationary, as described,

when gathering the butter.

Having thus described my invention,` what I claim as new, and desire tosecure by Letters Patenla'is- In combination with the revolving box A,the interior revolving shaft F and arms c c, tegetherwith the clasp H'and pin I, the whole constructed and operating substantially as and forthe purpose herein described. i

In witness whereof, I have'hereunto set my hand and seal.
